DELOS MOULTON, OF ELGIN, ILLINOIS, ASSIGNOR OF ONE-HALF TO ISAAC H. WARREN, OF ELGIN, ILLINOIS.

NozzLE.

Specification of Letters Patent.

Patented Oct. 1, 1907.

Application filed February 8, 1906. Serial No. 300,124.

To all whom it may concern:

Be it known that I, DELos MOULTON, a citizen of the United States, residing at Elgin, in the county of Kane and State of Illinois, have invented a new and useful Nozzle, of which the following is a specification.

This invention relates to improvements in nozzles, and more especially to that class thereof employed for spraying purposes, as, for instance, applying paint or coloring washes to houses, barns, and other buildings, distributing liquids over trees, plants, &c. for the purpose of moistening the same or destroying bugs.

The main objects of the invention are to produce a cheap and simple construction of nozzle expressly designed for the purposes stated, which is not liable to clog when in use, which consists of very few parts, and which may be readily taken apart for the purpose of a thorough cleaning when necessary.

Other objects and advantages of the invention will hereinafter appear and the novel features thereof will be particularly pointed out in the appended claims.

Referring to the drawing, Figure l is a side elevation of a nozzle embodying my improvements. Fig. 2 is a vertical longitudinal sectional view of the same.

Similar numerals of reference indicate similar parts in all the figures of the drawing.

In carrying out my invention, I employ a bowl or stationary chamber l, open at its upper end and connected at its lower end with a bored stem 2, arranged at an angle thereto. Threaded in the outer end of the stem 2, may be a supply hose or pipe 3.

The upper end of the bowl or stationary chamber 1 may be provided with a removable cap or cover 4, provided on its underside with an interiorly threaded annular flange 5, engaging similar threads formed exteriorly on the upper end of the bowl or chamber 1. The cap or cover may be further provided with a central opening 6, and, upon its underside with a counter-sink or annular recess 7.

The bowl 1 is provided with a cavity 8, the diameter of which preferably decreases towards its lowermost end or bottom, and at its front the wall thereof is provided with a discharge-opening 9.

Located within the cavity of the bowl is a plug l0, l

open at its lower end, and having its exterior tapered to agree with the cavity 8, or given any other shape in accordance with that of the cavity. As con-` the counter-sink or annular recess 7, and from the` center of said boss there rises a stem 12, upon which vis a wheel or handle 13, preferably secured in position by means of a screw 14. The plug is provided with a cavity 15 in its underside, and the wall thereof may be provided 'with various shapes and sizes of discharge-openings. In the present instance, 1G, designates two converging openings designed to discharge through the opening 9, and the jets from the two openings are designed to cause a misty spray or discharge. Further around is a slit-shaped discharge 17, which will produce a fan-shaped discharge, and still further around is an ordinary circular discharge, 18.

These openings may be varied at will, and in this manner all shapes of sprays produced. From the bottom of the bowl l, there in this instance, rises a scraping-post or pin 19,l the same extending upwardly into the cavity 15 of the plug l0 and terminating short of the dome of the same. The post or pin it will be observed is stationary with relation to the plug, and lying in close proximity to the interior thereof, it is in the path traveled by the various discharge-openings, 16, 17 and 18, so that, by occasionally turning or rotating the aforesaid plug by means of the handle or wheel 12 the pin or post will scrape around the wall of the cavity l5 and thus cleanse the wall by removing any adhering deposits The pin or post may be given any other shape desired, it being simply a scraper, and it may be mounted directly within the bottom of the bowl l, or, as shown in a removable plug 20, threaded in an opening 21, formed in the bottom of the bowl. This latter construction is preferred, inasmuch, by removing the plug 20 and the cap 4 the whole interior of the device can be readily and perfectly cleaned. v

The operation of the invention will readily suggest itself from the foregoing description. The liquid, whatever it may be, is provided by the pipe 3, flows into the stem 2 and finally into the cavity 15 of the plug 10. The plug l0 is rotated so as to bring the proper discharge-opening opposite or in line with the discharge 9 and the liquid is discharged through the latter opening in a shape or degree governed or determined by the size and shape of the discharge opening of the plug 10. If, at any time the plug 10 should become clogged, which is more likely to be the case where coloring liquid, such as white-wash is being discharged, a partial or entire rotation of the plug through the wheel l2 will serve to remove all deposit adhering to the wall of the cavity l5 of the plug.

It will furthermore be seen that the entire nozzle is composed of very few and simply constructed parts all of which are readily removable,

Having described my invention, what I claim is:

l, The combination, in a nozzle, of a hollow bowl pro vided with a lateral dischargeopening, a hollow plug mounted for rotation therein and provided with a dischargeopening adapted to be brought into alinement with the discharge-opening of the bowl, and a scraping device extending in said hollow plug.

2. The combination, in a nozzle, of a hollow bowl provided with a lateral discharge-opening, a hollow plug mounted for rotation therein and provided with a lower open end and above the same with a discharge-opening adapted to be alined with that of the bowl, and a scraping post or pin rising from the bottom of the bowl and extending into the open lower end of said hollow plug.

3. The combination, in a nozzle, of a hollow bowl, a plug mounted for rotation thereiny discharge openings formed in the bowl and plug, an opening formed at the bottom of the bowl, a removable plug therefor, and a scraping device carried thereby and extending upwardly into the hollow plug.

4. The combination, of the bowl 1 provided with a lateral hollow stem adapted to receive a supply-pipe and having
